Sandisk Extreme HD Video or Sandisk Ultra for Z990?

I am going to buy a SDHC card. But confused between the below two cards.

1. (13.47$) http://www.flipkart.com/sandisk-extreme-hd-video-sdhc-8-gb-30mb-s-rtl-pr-class-10-memory-card/p/itmczcrqujs8zkjk

2. (8.62$) http://www.flipkart.com/sandisk-ultra-sdhc-8-gb-30mb-s-class-10-memory-card/p/itmdaw7eduvzcj2m

I am looking for a good card to shoot in RAW and HD video..

Your suggestion regarding this will be highly appreciated.

Thanks.

I use the Extreme with my Z990 (and my Z915) and it works very well..especially when shooting video with no lagging or stuttering.

For the Z990, Ultra should be more than enough.

Thank you for your suggestions.

@Sactojim,

1. Can you provide the approximate write speed for this extreme hd video card.

2. How much time it takes to come back from shooting raw to an operational state?
3. Does it lag if the card is filled with more than 80% of data?

I just want to know if its really worth paying extra for the extreme hd card. Else i will get two Sandisk Ultra 8 GB.

Does anyone know what is the maximum speed the Z990 writes to the SDHC?

Thanks.
